I do tube crochet and have used Nymo thread. I noticed there are different sizes, which size would you recommend for size 8 seed beads?
The inside hole measurement of an 8/0 seed bead is 1.2mm. The largest size of Nymo® thread is D which measures 0.30mm. This size thread will go through the hole doubled or quadrupled. Whenever selecting thread for a project, it is best to choose the heaviest thread possible, factoring in the size of the bead hole as well as how many times the thread will pass through the bead.
Size #1 Silkon® bonded nylon thread is an excellent choice for crochet with size 8/0 seed beads as well. The thread is thicker than the Nymo and works well with a 1.5 size crochet hook.
